On article #1 in France: Hands-on with DxO ONE (270 comments in total)
In reply to:

DRDL: Number one in DP's awards and no images to compare? At least one reviewer did
say that the image quality was not as good as his iphone 6, so this seems like a non starter for me!

Well, that would be a highly suspect assessment, as the One has a far larger lens and a sensor with almost twice as many photosites, each of which is much larger than the iPhone's. Not to mention that the people who run DXO are not exactly incompetent, which they would have to be to make a camera that big that performs worse than the iPhone's. In fact, I ran a quick comparison right after I got my One for Christmas, photographing a scene in my front yard with the One attached to my iPhone 6S Plus and then with the iPhone's camera. I then viewed the images on-screen. The iPhone's image is quite good, as expected, but the One's is quite obviously superior—also as expected. Unless the reviewer you mention doesn't realize that color-balance differences are not a reflection on inherent quality, I'd say that he doesn't know what he's talking about, and clearly never examined comparable images side-by-side as I did. So far, I'm quite happy with the One.

On article AP cuts ties with Pulitzer-winning photographer (166 comments in total)

Re cropping vs content alteration: the focal length used for the photo is wholly arbitrary, and therefore so is the field of view and therefore the amount of potentially extraneous material. Nothing holy and inviolable is graven in stone regarding the FL, FOV, or peripheral material in a photo at the moment of exposure. There is no moral obligation for a photograph as published to contain anything peripheral to the focus of interest, even if inclusion of that peripheral matter would alter the viewer's understanding of the situation, any more than it's incumbent on the photog not to 'crop' by using a longer FL. Cropping is OK; alteration of included subject matter is not.

Re Contreras' technical skills: Awesomely clumsy! Some 'donor' material of the image is right on the other side of the fighter's right forearm, and more near the Rt edge! It's as though he wasn't even trying to disguise his alteration. Worst thing since the cloned plumes of battle smoke in Lebanon a few years ago.

After more testing, I'm absolutely flabbergasted. In the corners, at the optimal(?) aperture of f/5.6 the new AF-S Nikkor 24-85mm f/3.5-4.5G lens simply blows away the new AF-S Nikkor 24-120mm f/4G at both 24mm and 85mm. The '120 produces severe smearing and chromatic aberration in the corners, while the '85 yields a surprisingly better image, not as good as the one from my AF-S Nikkor f/1.4G 24mm prime, but a heck of a lot closer to that image than to the one from the 24-120.

I wonder if my copy is defective. If it's in-spec, I see little reason to choose the '120 over the '85, given the above and what I described in my last post, the size and weight advantage, and the cost saving of more than half. You'd have to need to spend a lot of time between 85 and 120 mm to justify the disadvantages of the '120.

Next: compare the new 24-120 with the old.

I'll be sending this lens to Nikon USA for evaluation. If there's no defect, I'm returning it.

I used the old 24-120 VR for walk-around on my D700, but when the D800 came out, after the new gold-banded 24-120 VR became available, I got both. Now, this combination is of daunting mass and volume, so I decided to consider the new (but non-gold banded), much smaller and lighter 24-85 VR, as I rarely use the extra focal length of the 24-120. I received this lens just yesterday, and after reading the opprobrium heaped on this poor little lens in this forum, I ran some tests of my own.

The results at 85 mm are surprising. At mid-apertures, the central-zone performance is barely distinguishable from that of the new 24-120 at 85 mm. There is very slightly less resolution and contrast--viewed at on-screen magnifications that begin to visualize individual pixels in the image. Even more surprisingly, at the edges near the corners, the ONLY difference I can see is slightly more chromatic aberration in the 24-85.

Next, a test at other FLs and out to the corners. Stay tuned.

Prediction: the announced price of $7195 for the new apo aspheric Summicron 50mm (!) will prove to be erroneous. The price is completely unreasonable--higher than any other M lens except the $10,995 Noctilux, more even than the exotic 21mm f/1.4--and almost twice that of the 50mm f/1.4 Summilux, which would mean no market position at all for it!

And yet B&H just listed it--for, yes, $7195!

It's simple: single-exposure image files, computer displays, and printed images represent ARBITRARY LIMITATIONS re the objective standard for the dynamic range that can be represented, i.e., what can be encompassed in real time by the human visual-perception system.

To enshrine the limits of what can be represented by a print of a raw single-image file on a sheet of paper is to enslave print photojournalism to an incidental, inadequate 150-year-old standard. Elliot thinks this is more honest why?

It is this arbitrary, limited standard--not the use of accurate HDR--that represents distortion of the truth. Conscientious, conservative HDR to simulate the same dynamic range as the human eye is nothing more than a way to make an artificial representation MORE honest.

By way of a fairly trenchant analogy, the same objections were voiced with: stereo vs. mono; color vs. B&W; talkies vs. silent films. Each was vilified despite overcoming an arbitrary limitation. I rest my case.
